Frequently asked questions about Summer Special 2026

What is a passive cooler?

A passive cool box, often referred to as a cool box without electricity, is an insulated container that keeps food and drinks cool without relying on an external power source.

The principle is very simple! Before use, the cool box is filled with ice packs or ice cubes. These ensure a low internal temperature, which is maintained for as long as possible thanks to the box's high-quality insulation. Passive cool boxes are the perfect companion for anyone who values flexibility and independence, whether camping, picnics or other outdoor activities.

How long do food and drinks stay cool in the Petromax cooling products?

The Petromax cooling products are designed to keep your food and drinks cool for a long period of time without electricity. The Petromax cool boxes can keep your supplies fresh for up to 12 days by using an ultra-passive cooling system powered by ice or ice packs. The cooler bags offer up to 6 days of cooling, while the cooler backpacks can keep your food and drinks cool for up to 8 days. These periods can vary depending on the outside temperature and usage, but they offer you the security of always having fresh food available, even on long trips.

Is the cooler bag also suitable for the beach?

Definitely. Waterproof cool bags protect the contents from sand and splashes. Thanks to the sturdy outer shell, the bag stays stable even when placed on uneven ground.

Passive vs. active cooler: Which one is right for me?

The choice between passive and active cooling depends on your individual needs. Passive coolers like those from Petromax offer you complete independence from the power grid and are ideal for remote campsites. They operate completely silently and only require ice or cooling packs as an energy source.
Active coolers, on the other hand, provide constant temperatures but need a power source. For a detailed comparison of all systems, we recommend our guide on active vs. passive coolers.

Are the Petromax cool boxes waterproof?

The Petromax cooler bags and cooler backpacks are made of water-repellent material and have waterproof zippers. This ensures that your contents are optimally protected, even if you are traveling in damp or wet environments. The cool boxes are also robust and offer a high level of protection against moisture. These features make our cooling products reliable companions in all weather conditions and outdoor activities.

How can I keep my cooler bag cold for longer?

Store the Cooler Bag in the shade before use or chill it briefly. Pack food and drinks as pre-cooled as possible and distribute the cooling packs evenly. The fuller the Cooler Bag, the longer the temperature stays stable.
